When animals undergo the process of cellular respiration, they release carbon dioxide into the atmosphere. When animals die and start to decay aided by organisms called decomposers, carbon dioxide is also emitted into the atmosphere. When humans burn fossil fuels, carbon dioxide yet again enters the atmosphere.

Answer:

B.) Carbon dioxide in the atmosphere is carried through the ocean with precipitation and plants also use carbon dioxide in the atmosphere for photosynthesis.

Explanation:

The original answer choices for this question are the following:

A.) Carbon cycle ends when carbon dioxide is released when plants die and decompose.

B.) Carbon dioxide in the atmosphere is carried through the ocean with precipitation and plants also use carbon dioxide in the atmosphere for photosynthesis.

C.) Carbon dioxide travels through the atmosphere through photosynthesis and cellular respiration.

D.) Plants use carbon dioxide to perform cellular respiration and release carbon dioxide as a by-product.

Some of you may have different answer choices, so please be careful and read over the list I put in case your question is different from mine. I answered this correctly on a Biology test, so I hope this comes to your help! :)

Which of the following is a factor that, by itself, does not promote widespread changes in allele or genotype frequencies? a. Ne

defon

Answer:

A new mutation

Explanation:

A mutation refers to the random changes in the DNA of organisms. A mutation changes the allele and genotype frequencies by the introduction of a new allele in the gene pool.

However, mutations are not the major factor responsible for changes in the gene pool of a population as mutations are rare. The rate of mutations is very slow and does not allow it to serve as a major factor to change the allele and genotype frequencies.

The body's ability to maintain a relatively constant internal environment is called homeostasis. This stability can be challenge

Anit [1.1K]

Homeostasis can be defined as the state of maintenance of the constant internal conditions by the living organisms. The homeostasis is maintained by the body so that it may function properly. The homeostasis will be disturbed by the reduced intake of the food and water. Healthy intake of water and food is essential in maintaining the homeostasis of the body. The elevated or depressed blood pH along with extreme body temperatures will also disturb the homeostasis of the body making the person sick. Moreover, certain infectious organisms also alters the homeostasis of the body.

Hence, all the options are correct.

PauseStopReplay Word Translate Which base is found only in RNA nucleotides?

AveGali [126]

The base found in RNA nucleotides, but not in DNA, is uracil.

RNA and DNA share three bases: adenine, cytosine, and guanine. However, for the fourth base, DNA has thymine while RNA has uracil. When forming base pairs, cytosine bases are matched with guanine, while adenine bases are matched with uracil or thymine.
